Sex difference was detected by Wald test. Models controlled for ethnicity, maternal IQ, maternal demoralization, maternal hardship and maternal satisfaction during pregnancy, maternal prenatal exposure to PAH and BPA, child sex, child age in months at the time of the CBCL administration, and specific gravity. *p < 0.05, **p ≤ 0.01, #p < 0.001. |
